OIL-SPBAYING DEVICE.

Application filed June 2, 1925. Serial at. 34,387.

To all whom it may concern:

Be it known that I, lVILLmM B. BROWN, a citizen of the United States, residing in the county of Nash, near Rocky Mount, in the county of Edgecombe and State of North Carolina, have invented certain new and useful Improvements in Oil-Spraying Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in oil spraying devices and has relation more particularly to a device of this kind especially designed and adapted for use in connection with water gas sets, and it is an object of the invention to provide a device of this kind wherein the spraying nozzle is moved up and down with respect to the carburetor and a hydraulic medium and wherein the oil and water at all times are kept entirely separated whereby the efficiency of the gas set is materially increased.

It is also an object of the invention to provide a spraying device of this kind constructed in a manner whereby the oil delivered to the nozzle may be preheated.

An additional object of the invention is to provide a device of this general character wherein the flow of oil thereto isunder con' trol of a hydraulic medium, the various movable parts being assembled so as toeliminate the possibility of the oil and water mixing.

The invention consists in the'details of construction and in the combination and ar rangement of the several parts of my im proved oil spraying device. whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view partly in section and partly in elevation illustrating a spraying device constructed in accordance with an embodiment of my invent-ion;

\ Figure 2 is an enlarged fragmentary View partly in section and partly in elevation illustrating in detail the features comprised in 5 the device as herein embodied.

a discl se is the necessari s drew ings, C denotes a fragment of the upper portion of a carburetor of a well known type employed in connection with water gas sets and through the top wall of which is slidably disposed an elongated hollow shaft S.

cylinder A through which the shaft or stem S is axially disposed, the heads 4 of said cylinder A being provided with a stuffing box 5 through which said shaft or stem S is directed to eliminate leakage. Fixed to the portion of the shaft or stem S within the cyl-- inder A is a piston head 6 held in desired position upon said shaft or stem the nuts 7 threaded thereon and contacting with the piston head 6 from above and below. In communication with the opposite ends of the cylinder A. are the pipe lines 8 comprised in ahydraulic system of any desired type, and when the piston head 6 is forced downwardly under hydraulic pressure the lower or bottom nut 7 will contact with the lower or bottom head 4 of the cylinder A preventing the piston head 6 from cutting off the rower pipe line 8 to prevent the piston head 6 being moved upwardly under hydraulic pressure. The upper nut 7 has contact with the upper head 4 to prevent the head 6 from going too far in its upward travel with respect to the upper pipe line 8.

Supported by the upper end of the cylinder A through the medium of the legs 9 is the oil cylinder B into which the upper portion of the shaft or stem S extends from below through the stuffing b0 10 carried by the lower head 11 of said cylinder B. This upper portion of the stem or shaft S is within the cylinder B at all times irrespective of the lengthwise movement. of the shaft or stem S under the influence of the hydraulic pressure upon the piston head 6.

Depending from the upper head 11 of the cylinder B is a needle valve 12, said needle valve being in threaded engagement with or otherwise attached to said head. When the shaft 9 5 at substantially the communication with the line 14 at a point closely adjacent to the cylinderB is a steam line 15.

In practice, oil enters the cylinder-B through the oil line 14 preferably under fift )ounds )ressure aer souare inch. When the shaft or stem S is forced downwardly under requisite hydraulic pressure, the needle valve 12 is released and at the same time the nozzle N is forced down into the carburetor. This results in a quick valve release to permit the oil to run down through the shaft or stem S and out through the nozzle N. After a proper amount of 011 has been run, steam is turned in through the line 15 through the cylinder B and the pipe or stem S and out through the nozzle N to purge the nozzle and clean out the ear buretor. The nozzle N is then raised up out of the carburetor under requisite hydraulic pressure and which operation results in the closing of the flow through the pipe or stem S which prevents oil from leaking down into the carburetor while the water gas run is off. It is also to be understood that the oil passing through the pipe line 12 may be readily preheated before delivered within the cylinder B and thus provide for the economy in gas production obtained by such preheating.

From the foregoing description it is thought to be obvious that an oil spraying device constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

1. claim 1. In combination with the carburetor of a water gas set, an oil spraying device comprising a tubular shaft shdably extending within the carburetor through a wall there-.

of and throu 'h which oil is ada )ted to flow a pair of spaced aligned cylinders arranged exteriorly of the carburetor, said shaft being disposed through one of said cylinders and extending within the other, a piston head carried by the portion of said shaft within the first named cylinder, said'iirst named cylinder being provided with means for admitting fluid to move said piston head and shaft in opposite directions, a valve within the second cylinder adapted to close the oil flow through the tubular shaft when the shaft and piston head are moved in one direction, and an oil pipe discharging with in the second cylinder.

2. In combination with the carburetor of a water gas set, an oil spraying device com- I prising a tubular shaft slidably extending within the carburetor through a wall thereof and through whichoil is adapted to flow, a pair of spaced aligned cylinders arranged exteriorly of the carburetor, said shaft being disposed through one of said cylinders and extending within the other, a piston head carried by the 1 portion of said shaft within the first named cylinder, said named cylinder being provided with means for ad mittmg fluid to move said piston head and shaft in opposite, directions, a needle valve,

carried by. and extending within the second named cylinder, said needle valve being received within the shaft to close the oil flow through the tubular shaft when the shaft and piston head are moved in one direction,

and an oil pipe discharging within the second cylinder.

3. In combination with the carburetor of a water gas set, an oil spraying device comprising a tubular shaft slidably extending within the carburetor through a'wall thereof and through which oil isadapted to flow, a pair of spaced aligned-cylinders arranged exteriorly of the carburetor, said shaftbeing disposed through one of said cylinders and extending within the other, a piston head carried by the portion of said shaft within the first named cylinder, said first named cylinder being provided with means for admitting fluid to move said piston head and shaft in opposite directions, means adapted to close the oil flow through the shaft when the shaft and piston head are moved in one.

In testimony whereof I hereunto affix my signature.

WILLIAM 1%. BROWN.
